a guess b but no clue'

 

Av fistulae decrease TPR and increase C.o and increase pulse pressure

 

D. plz post the right answer & the source of the Q, thanx

 

Maybe E.

Akua

 

d) high output failure

 

TPR will be decreased since its a fistula...easy way to the vein.
Cardiac output will be increased due to increased venous return.
And pulse pressure will increase because of decreased TPR.

 

yes but there will be more blood going to the heart as well, means heart will have to pump more blood out which will inc TPR, INC CO AND INC PP
SO MY ans is DDDDDDDD

 

AV fistula decreases total peripheral resistance as it creates a sort of bypass for blood... cardiac output is increased n so is pulse pressure.. option D

 

Answer is D Good job guys!
